What is one of the stuctures a cell uses to live, grow, and reproduce?

Answer 1

Nucleus.
Its like the very center of the cell. So kind of like the brain in humans.
This is the most important structure and I could list more but you said "one of the structures".

To show that this isn't all I know, go to this website:

To find out more. Its really cool with the movies and the interactive pictures. You learn while you play.

Have fun and I hope this helped!
P.S. This site is cool too:

Answer 2

The WHOLE cell has a role in the life and reproduction of itself:

Cytoplasm (illustration)
The cytoplasm is fluid inside the cell that surrounds the organelles.

Endoplasmic reticulum (ER) (illustration)
This organelle helps process molecules created by the cell and transport them to their specific destinations either inside or outside the cell.

Golgi apparatus (illustration)
The golgi apparatus packages molecules processed by the endoplasmic reticulum to be transported out of the cell.

Lysosomes and peroxisomes (illustration)
These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components.

Mitochondria (illustration)
Mitochondria are complex organelles that convert energy from food into a form that the cell can use. They have their own genetic material, separate from the DNA in the nucleus, and can make copies of themselves.

Nucleus (illustration)
The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material. The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell.

Plasma membrane (illustration)
The plasma membrane is the outer lining of the cell. It separates the cell from its environment and allows materials to enter and leave the cell.

Ribosomes (illustration)
Ribosomes are organelles that process the cell’s genetic instructions to create proteins. These organelles can float freely in the cytoplasm or be connected to the endoplasmic reticulum (see above).

Answer 3

3 eaasily obvious answers.

1. DNA. It is responsible for creating another cell of same structure.

2. RNA. This is the messenger responsible for the replication process of the DNA

3> Vacuole. This is the structure which elongates and splits to form a second cell.

Answer 4

The Nucleus

Answer 5

nucleus: it contains all the DNA which codes for proteins and genetic information that allows the cell to function and perform these activities.

Answer 6

cells need something to feed on if they want to reproduce etc.

Answer 7

matter
